Wales fullback Liam Williams will miss their opening Six Nations match after being handed a three-game ban following his red card in Scarlets' defeat by Cardiff Blues last week in the PRO14.
The 29-year-old will miss Ireland's visit on Feb. 7 after he was sent off for diving into a ruck and making contact with the head of Blues forward Shane Lewis-Hughes.
"The player is suspended from participating in the next three meaningful fixtures for which he is fit and available for selection," PRO14 said in a statement.
The suspension will also see Williams miss two Scarlets games.
England's Kyle Sinckler is also set to miss his side's opening match against Scotland after being banned for two weeks from rugby for swearing at a referee.
